228 DR. O. STAPF ON THE FLORA OF MOUNT KINABALU, 
cystolithis crebris linearibus conspersa, trinervia, nervis ad acumen productis, venis 
transversalibus distinctis. Stipule inter folia cicatricem transversam conspicuam 
relinquentes. Flores masculi in glomerulis parvis in spicá simplici vel parce 
compositá, axillari, gracillimá, 14 poll. longa dispositi.  Perigonium 4-partitum ; 
segmenta ovata, 2 lin. longa. Stamina 4. Ovarium rudimentarium minutum. Flores 
Jeminei in cymis axillaribus brevissimis, multifloris, glomeruliformibus. Perianthium 
3-partitum ; segmenta valde inzqualia, intermedium demum 4 lin. longum, lateralibus 
3-plo majus. Achznium suboblique globoso-ovoideum, valde compressum, $ lin. 
longum. 
On the Tampassuk River, alt. 3000 feet (Haviland, 1229). 
Allied to P. smilacifolia, Wedd., but very distinct by the winged stem and the very 
short and broad petioles. 
PILEA CRASSIFOLIA, Stapf, n. sp. Herba glaberrima. Caulis quadrangularis, sulcatus, 
flavido-virescens. Folia opposita, subzequalia, petiolo 14-14 poll. longo suffulta, 
oblonga vel oblanceolata, 2-3 poll. longa, 7-9 lin. lata, basi minute biauriculata, 
apice acuminata, in margine, basi exceptá, crenato-denticulata, crassa, exsiccando 
nigro-viridia, subtus pallidiora, utrinque cystolithis creberrimis obsita, et minute ni- 
gropunctata, Flores masculi in glomerulis densis, parvis, in spicis plerumque parce 
compositis, solitariis vel paucis, in axillis foliorum dispositis. Perigonium 4-partitum; 
segmenta ovata. Stamina 4. Ovarium rudimentariuw minutum. Flores feminei 
pauci cum masculis in centro glomerulorum. Perianthium tripartitum; segmentum 
intermedium lateralibus majus, cucullato-obovatum, apiculatum. Ovarium 
ovoideum ; stigma incrassatum. 
At 3000 feet (Haviland, 1339). 
Allied to P. smilacifolia, Wedd., but distinct by the very thick and crenulate-denti- 
culate , leaves, the transversal veins of which are hardly visible, and the abundance of 
cystoliths, amongst which black dots are scattered over the lower surface of the leaves. 
A Philippine specimen from the island of Panay (Vidal, 3863) comes still nearer, but it 
has rather asymmetric leaves, with very unequal and often short petioles.

disticha, petiolo 1-2 lin. longo suffulta, late linearia vel lanceolato-linearia, 14-24 
poll. longa, 4 lin. lata, basi inzequalia, in latere extus spectante in petiolum auricu- 
latum decurrentia, acuta, a medio vel in summa tertiá parte grosse arguteque dentato-

nigro-punctata, subtus in costa necnon in nervis adpresse strigillosa, pallide fusca, 
' punctulis crebris obsita, nervis lateralibus subpatulis utrinque 8-11, sepe valde 
indistinctis vel parenchymate plane obtectis. Stipulz oblique ovate, acute vel
